GEOPRESSURED GEOTHERMAL FAIRWAY EVALUATION AND TEST-WELL SITE LOCATION FRIO FORMATION, TEXAS GULF COAST

摘要

Tertiary strata of the Texas Gulf Coast comprise a number of erogenous depositions! wedges, some of which thicken abruptly at their downdip ends as a result of contemporaneous movement of growth faults and underlying salt. The Frio Formation, one of these wedges, has been studied regionally by means of a grid of correlation cross sections aided by micropaleontological control. By means of these sections, the Frio was subdivided into six map units;maps of sandstone distribution within these units delineate principal elongate sandstone trends parallel to the Gulf Coast composed of deltaic, barrier-bar, and strandplain sandstones.
